32 GTR and other model , upgraded clutch bleeding/fixing tip

Skyline GTR 1991 ......
but will be the same for R33 - R34 - Stagea and any other Nissan model with a servo assisted clutch master cylinder.......

There are several factors to act against your simple installation of a Multi plate clutch .
Trial and error is long winded and frustrating .... so , if you fit a multi plate clutch to an already fully working car , ( or even just a new clutch ) and you can`t get a clutch pedal that will allow engagement of any gear , rather than ripping off the standard Damper system - replacing all rubber pipe work with Braided and replacing all the rubbers/cylinders etc !!!

try testing to see if servo push rod is directly contacting with the Master cylinder push rod , mine was not , the previous owner had wedged a piece of 7mm thick rubber disc between the push rods ???? and the push rod on the master cylinder had just cut through it ( a strange idea given that the end of the push rod is hollowed out !! )
the adjuster inside the car was at its max and so to cure

I have fitted a bolt between the 2 push rods , it is about 20cm long and fits tightly with its head into the servo push rod end ( it has a cup location ring that the bolt sits in ) .

To test this simply loosen the 2 nuts holding the master cylinder to the servo unit , undo all the way so the master cylinder can move freely in and out of the servo , get an assistant to sit in the car and slowly push the clutch pedal downwards , holding the master cylinder IN with you hand you will fee the push from the servo push rod , if it is instant then your problem is elsewhere ( bleeding / bent clutch arm / defective lever post for clutch arm / air in damper system (has bleed nipple on small junction box opposite slave cylinder on chassis )

It`s just a tip , but 1 that could save months and money !!
